What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeUsing optical coherence tomography angiography (OCTA) to evaluate retinal microvascular changes in sarcoid and tuberculous (TB) posterior uveitis.
methodsCross-sectional observational study includes 30 eyes. FFA and OCTA images were acquired. OCTA images were analyzed for areas of capillary hypo-perfusion, disorganization of the superficial and deep capillary plexuses (SCP and DCP) and intraretinal cystoid spaces and for measuring the size of the foveal avascular zone and vessel density (VD) in the SCP and DCP.
resultsA total of 11 eyes were associated with TB and 19 with sarcoidosis. By OCTA, 100% had areas of capillary non-perfusion, 36.7% choroidal voids, 30% disorganization of the SCP and DCP and 26.6% intraretinal cystoid spaces. The VD of the DCP was significantly lower in the TB group. On comparing OCTA and FFA, parafoveal ischemia was detected more frequently on OCTA and macular edema more frequently on FFA (P = < 0.001). The BCVA was not significantly correlated with the VD of the SCP or DCP.
conclusionOCTA can be used in detection of early microvascular changes, segmenting retinal layers and localizing abnormalities. The presence of these changes may aid in the diagnosis of TB and sarcoid uveitis, for prognosis, follow-up and may be the only choice when FFA is contraindicated.
